Fcuking hilarious, reminds me of a Cpl's mess do once where on the table were placed miniture bottles of champagne!
These mini bottles of champagne however and unbeknown to the said Cpls sat at the table, contained blowing bubbles!
Oh how we laughed once they had downed the bottles and then seconds later thrown the contents of their stomachs up all over the table, to the horror of the Pad's wives sat around them!
